Product Description

The EBC S1KF2148 kit delivers a matched front-axle brake package combining vented 316 mm rotors with high-quality Ultimax™ street brake pads - an upgrade over many stock braking systems, particularly for everyday driving and commuter use. The rotors' iron construction and corrosion-resistant coating help ensure durability and resistance to environmental stress, while the machining balance reduces vibration and enhances braking smoothness.

The Ultimax 2 pads offer consistent, low-dust braking with pre-installed shims and chamfering to minimize noise and uneven pad wear. With direct-fit engineering, this kit mounts cleanly on compatible vehicles without modifications - provided bolt pattern, rotor hub specs, and caliper clearance match OEM standards. It's a solid choice for drivers seeking reliable, OEM-style braking performance with improved rotor lifespan and pad quality. As with any brake kit covering multiple models, it is essential that you verify full compatibility with your vehicle's year, make, model, trim, and brake system specs before installation.
